Brannan alleged that his ex-girlfriend confronted him at Oxygen Health and Fitness Gym in the 11000 block of U.S. Highway 1 in North Palm Beach on Valentine's Day.

He also said Capriati called him dozens of times while he was at work one day in January, even showing up there later and banging on windows.

Through her representatives, Capriati this month denied any wrongdoing.

Capriati burst onto the tennis scene at age 14, more than 20 years ago, and won 14 titles, including three Grand Slams, as well as a gold medal at the 1992 Olympics.

She had some off-court troubles while still in the prime of her career, but shook them off and returned to the sport at the top of her game, claiming the Australian Open and French Open crowns in 2001.

ESPN reporter Britt McHenry

ESPN suspended reporter Britt McHenry for a week after a video of her berating a towing company employee surfaced Thursday. On the roughly one-minute long video that was captured by a surveillance camera, McHenry says to an employee at a register: "I'm in the news, sweetheart. I will (expletive) sue this place." The employee tells McHenry she's being recorded, but it doesn't stop her from continuing her rant. Here are some other celebrities who have fallen from grace.
